What Is Attention Deficit Hyperactivity Disorder (ADHD)?

Many people have heard of ADHD. It may make you think of kids who have trouble paying attention or who are hyperactive or impulsive. Adults can have ADHD, too. About 4% to 5% of U.S. adults have it. But few adults get diagnosed or treated for it.

Who gets adult ADHD? Every adult who has ADHD had it as a child. Some may have been diagnosed and known it. But some may have not been diagnosed when they were young and only find out later in life.

While many kids with ADHD outgrow it, about 60% still have it as adults. Adult ADHD seems to affect men and women equally.

Adult ADHD Symptoms

This can cause trouble in many parts of life -- at home, at work, or at school. Getting treatment and learning ways to manage ADHD can help. Most people learn to adapt. And adults with ADHD can develop their personal strengths and find success.

These may affect you a lot, or they may not bother you much. They can be problems all of the time or just depend on the situation.

No two people with ADHD are exactly alike. If you have ADHD, you may be able to concentrate if you’re interested in or excited about what you’re doing. But some people with ADHD have trouble focusing under any circumstances. Some people look for stimulation, but others avoid it. Plus, some people with ADHD can be withdrawn and antisocial. Others can be very social and go from one relationship to the next.
